Quick Answer: Free Kindle books are usually limited-time promotions that authors run to gain visibility. Most last 1-5 days before returning to regular price.

Why Do Authors Make Books Free?

Authors don't give away books out of charity — it's a marketing strategy. Here's why they do it:

  • Gain new readers — Free books attract readers who might buy the author's other books
  • Get reviews — More downloads = more potential reviews, which boost visibility
  • Launch a series — Making book 1 free hooks readers who then buy books 2, 3, 4...
  • Boost rankings — High download numbers improve Amazon search rankings
  • Promote new releases — Authors often make older books free when launching new ones

How Long Do Free Deals Last?

The duration depends on how the author set up the promotion:

KDP Select Free Promotions (Most Common)

  • Authors enrolled in KDP Select get 5 free days per 90-day period
  • They can use all 5 days at once or spread them out
  • Most promotions run 1-3 days

Price Matching (Permafree)

  • Authors can make books permanently free by pricing them at $0 on other platforms
  • Amazon then "price matches" to $0
  • These books stay free indefinitely

Countdown Deals

  • Books discounted (not free) for up to 7 days
  • Price gradually increases back to normal

Why Do Deals Expire?

Several factors cause free deals to end:

  1. Promotion period ends — The author's scheduled free days run out
  2. Amazon limits — KDP Select only allows 5 free days per quarter
  3. Author decision — Authors can end promotions early if they want
  4. Price match removed — Amazon may stop matching competitor prices

Important: Deals typically end at midnight Pacific Time. If you see a book that's been free for a few days, grab it before midnight PT!
